IMPROVEMENT IN GAS-REGULATORS FOR RETORTS Specification forming part of Letters Patent No. 207,052, dated August 13, 1878; application filed July 15, 1878.

To all whom it may concern:

Be it known that I, LEVI G. MOOAULEY, of West Chester, in the county of Chester and State of Pennsylvania, have invented a new and Improved Gas-Regulator for Retorts and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention is an apparatus for relieving the pressure of gas in retorts of gas-works by allowing it more rapid escape into the hydraulicmain when the pressure is too great. The apparatus is connected and co-operates with a steam-jet exhauster, which is used for exhausting retorts and forcing the gas into the hydraulic main.

In the accompanying drawing, forming part of this specification, Figure 1 is a partly-sectional elevation, showing my regulator applied to an. exhauster. Fig. 2 is a plan view of the regulator proper.

The steam-jet exhauster A is of the type or pattern illustrated in patent of E. Korting, No. 142,856, and is constructed on the principle of the well-known Gifiard injector.

B is the steam-induction pipe, and G the pipe leadingto gas-retorts. (Not shown.)

The gas-pressure regulator consists of the following parts, to wit: a water-holder, D; a concentric gas-holder, E, contained therein, a lever, F, which is fulcrumed at one end on a fixed support, a, attached to the water- .holder D, and adjustably connected at its free end with a vertical spindle or rod, G, which is extended downward and tapered to form the valve of the steam-exhauster A; and a short lever, I, which is also fulcruined on a fixed support, 0, and pivoted at its opposite or free end to the top of the gasholder E, and at an intermediate point, (I, to the long lever F. The latter is arched to allow for upward movement of the gas-holder E, and passes through elongated slots in the short lover I and its fulcrum 0.

The spindle G is screw-threaded, and the adjustable connection between it and the lever I is formed by screw-nuts, "c c, placed one above and the other below the eye formed on the end of the lever.

with water to a suitable height, and the gas from the retorts allowed to pass into the holder E through pipe K, its pressure therein will raise the holder more or less.

It is obvious that since any rise or fall of the holder E will raise or lower the bifurcated inner end of the short leverI correspondingly, the free end of the long lever F must also have a like movement, in consequence of the hinge-connection d between the two levers and since such vertical movement of the free end of lever F either raises or depresses the spindle G, it is further apparent that the valve H will be thereby partly or entirely opened or closed, according to the extent of variation in the height of the gas-holder D under the varying pressure of gas in the retorts. When the pressure is above a certain degree the spindle G is raised and valve H opened to allow the steam-jet to exhaust the retorts more rapidly, and thus relieve the pressure. On the other hand, when the pressure falls below a certain degree, the spindle B is depressed and the valve 1) closed to shut off the steam-jet.

The desired degree of pressure in the retorts is thus dependent on the action of the steainjet exhaust as governed by the action of the regulator; and the latter may be caused to relieve the pressure at different degrees by adjusting the nuts 6 e upor down on the spindleG, thus practically varying the weight of the holder E, which the pressure must suffice to overcome in order to open the steam-jet valveb. The connection between-the latter and the spindle may be eflected in various ways.

The regulator may be applied to various forms of fluid-injectors or exhaust apparatus besides that used in connection with gasae torts.

hat I claim is-- The combination, with the steam-jet appw ratus and the gasholder E, of the spindle G- and valve 7), and lever F, the latter having a flexible or hinge connection with said gas holder, as specified.
